Some parts of London are like a banana republic when it comes to elections. It will be interesting so see what caused such a massive mess up in Londons largest borough, Barnet, which is also home to Londons largest Jewish community and comservative voters.
Last year in Tower Hamlets:
An east London mayor has been removed from office and a poll declared void after he was found guilty of electoral fraud.
An Election Commissioner concluded Tower Hamlets mayor Lutfur Rahman breached election rules and must vacate his post immediately.
Four voters alleged he used "corrupt and illegal practices" in last year's election, which must now be re-run.
Mr Rahman, who denied any wrong-doing, has been banned from standing again.
At the special High Court hearing, Election Commissioner Richard Mawrey also ordered Mr Rahman to pay £250,000 in costs.
One of Mr Rahman's aides, Alibor Choudhury, was also found guilty of corrupt and illegal practices.
Tower Hamlets First, Mr Rahman's party, said the judgement was a "shock" and it was seeking further legal advice in relation to a judicial review.
Mr Mawrey - who sat as a judge - said the mayor had "driven a coach and horses through election law and didn't care".
